Answer 2

Răspuns: $\bf \red{\underline{~5^{2}~}}$

Explicație pas cu pas:

$\bf \big(5^2+10\cdot 5^2\big):11=$

$\bf 5^{2}\cdot\big(5^{2-2}+10\cdot 5^{2-2}\big):11=$

$\bf 5^{2}\cdot\big(5^{0}+10\cdot 5^{0}\big):11=$

$\bf 5^{2}\cdot\big(1+10\cdot 1\big):11=$

$\bf 5^{2}\cdot\big(1+10\big):11=$

$\bf 5^{2}\cdot11:11=\red{\underline{~5^{2}}}$
